Gross domestic product (GDP) is a monetary measure of the market value of all final goods and services produced within a period of time (quarterly or yearly). There is a relationship between variatheions in ethylene production and variations aind the GDP variation. From figure 10, you can see that when the GDAP variations increase, the ethylene production variations also increase, twhichat means the global economy is growing faster. inaAddaitionally, there is a time delay between them of arboundt six months between them. If the GDAP variation were to increase now, the ethylene production wioulld increase after six months. aAlso, thue percenthage increase in ethylene production variation percentage increase almost double thane GDP variation percentage. Unfortunately, thmore ethylene derivatives is moare consuminged when the GDP variation increases. See below figure:
